Welcome to SRP. I know about 'coming down from a buying spree'. I'm an expert on that. What you have gotten if it is a single bevel folding razor is a microtome. They are meant for slicing tissue samples.

Here is a post that I made on honing a microtome successfully to shave with. I would suggest it would be better for you to get a standard double hollow and start shaving with that. If you buy one pre honed that is your best bet.

Save the microtome for when you've gotten some honing under your belt and feel confident in your ability.
